1 Dollar - Elizabeth II Lady with an Ermine

The "Lady with an Ermine" is one of Leonardo da Vinci's four surviving portraits, painted around 1489–1490 and believed to depict Cecilia Gallerani, mistress of Ludovico Sforza, Duke of Milan. The painting remained in Polish private hands for centuries before being acquired by Prince Adam Jerzy Czartoryski in the late 18th century — it is now held in Kraków's Czartoryski Museum.
